I'm not even sure what this "bug/feature" is, how to reproduce it... Transparency handling is a complex issue, and HyperSnap 7 has many features for adjusting it, particularly for 32 bit images, where the "alpha" channel lets you set 256 level of transparency, from completely transparent (alpha = 0) to completely opaque (alpha = 255)...

Coming back to our year-old discussion of the bug/feature I've described here in the topic. I was not smart enough to appreciate the good size of this "bug", but over time I have realized, that actually is gives some extra superconvenient options when montaging parts of different similar images, say, a series of sequent screenshot. Now I am rather afraid, that this "bug" may be somehow fixed in some new version.

However it will be fine to get this "bug" as a feature. At the first, one can be sure, that his option will remain forever and will not be lost since some version. At the second, a user would get a control of this bugfeature in order to call it every time, when it is needed - and not when he does not need it.

Could you please consider adding this option intentionally as a splendid unique feature of Hypersnap?

Thanks!

I think your problem arises from auto-saving to GIF files. GIFs are now obsolete, I suggest auto-saving as PNG instead as a quick work-around.

Your suggestion is correct! Switching auto-save format between .PNG and .GIF gives the immediate result every time in the both side, even without HS restarting!
However it would be fine to detect the cause of this interesting effect. Please consides, that it has appeared in the later HS version and I have not change anything in my system in the meanwhile.

in which color mode is your screen, 32 bits per pixel or 24 bpp, or maybe 16?

Do you mean this settings under Windows XP: Display Properties -> Settings -> Color Quality? The number "Highest (32 bit)" is currently there.

Could not reproduce it in a quick test with your config file, but I think your problem arises from auto-saving to GIF files. GIFs are now obsolete, I suggest auto-saving as PNG instead as a quick work-around. Please also tell me in which color mode is your screen, 32 bits per pixel or 24 bpp, or maybe 16? Maybe setting the screen to the same mode I could reproduce the bug and find a fix...

OK, sorry for mix-up with password. Sent the file by email.

BTW I think, that this "transparency feature" is quite useful in some (even many!) situations. So the question is no to remove it, but rather take it under control in order to understand and be able to choose, whether white parts of the image being pasted will be transparent or not.

I got your message, and downloaded a file from RapidShare, but it does not accept the password... It would be better to just send it by email to [link=mailto:support@hyp...com]support@hyp...com[/link]

All the settings on your image look correct to avoid transparency. I don't know what else it could be, if you still have a problem after setting these values as your image shows, please save your configuration and send to me as email attachment, plus descirbe step by step instructions to reproduce the problem.

Support Check "Capture Settings" on the Capture ribbon tab, look at "Default background color for captures" and the "Opacity" setting next to it.
Also look at the "Image" ribbon tab, "Colors" frame, "Substitute" and see if you defined some color substitution with "Automatically apply to all captured images" option turned on.

I'm not sure about every option there. Could you please take a look yourself?

And one more notice. When I copy an image between HS different windows, it puts the image white parts as transparent. But when I swith windows and than come back, the pasted image become a regular. However if I witch to another application window and than come back, tha image white parts remain transparent. Does it give you any idea?

White color is automatically substituted with 100% transparent in all screen captures and when pasting images via OS clipboard from other app, but not in white color filled shapes. I don't know, have I made something accidentally when re-configured my HyperSnap or it's due some code changes in last versions. The problem persists after reloading Windows too.

Any idea, which option should I check to restore regular behavior?

Thanks!

BTW, am I the only who has headache with forum search? Search for a part of the keyword does not work (say, searching with "transp" does not return anything) and in Opera search does not work at all.

Exact HyperSnap version in use (from Help/About menu): 7.20.04
